Same, add new enumeration item for EINVAL.

[jlduran]

Put the new EINVAL descriptions on separate list items.

Note that no linting was performed on these man pages.

The useless Tn macros will also be removed, but:

mandoc: open.2:350:9: STYLE: referenced manual not found: Xr __acl_get_fd 2
mandoc: open.2:350:29: STYLE: referenced manual not found: Xr __acl_aclcheck_fd 2

Will not be removed, given those were recently introduced in 7a292504bad8467915f072f0576b2a07c76de1f5.
